+
+The default PIPX_HOME is `~/.local/pipx`, prior to the adoption of the XDG base
+directory specification after version 1.2.0. To maintain compatibility with older 
+versions, pipx will automatically detect the old paths and use them accordingly.
+For a map of old and new paths, See [Installation](installation.md#installation-options)
+
+To migrate from the old path to the new path, you can remove the `~/.local/pipx` directory and 
+reinstall all packages.
+
+For example, on Linux systems, you could read out `pipx`'s package information in JSON via `jq` (which you might need to install first):
+
+```
+packages=($(pipx list --json | jq '.venvs | keys[]' -r))
